The last patch has severely screwed something up with the game.
I have experienced a total system lockup 3 times on deskaluda and only that boss.
i have checked my dxdiag and done a scan of my steam game files and it just happened 5 minutes ago again…had to unplug PC as it was a Hard lockup.
It could be some conflict with EAC or something im not sure…but its becoming very annoying and im afraid to sign up for new kakul group incase it happens there.
